This Slow Cooker Sweet Potato Casserole combines creamy, spiced mashed sweet potatoes with a buttery pecan or oat topping — all made in the slow cooker. It’s a hands-off, crowd-pleasing side perfect for holidays or cozy dinners.

Ingredients

  • 4–5 large sweet potatoes, peeled and cubed
  • 1/2 cup (1 stick) butter or dairy-free alternative
  • 1/2 cup brown sugar (adjust to taste)
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/4 tsp ground nutmeg (optional)
  • 1/4 tsp salt
  • 1/3–1/2 cup milk (or plant-based milk)
  • 2 large eggs (optional, for structure)
  • Topping:
  • 1 cup chopped pecans or walnuts
  • 1/3 cup brown sugar
  • 1/3 cup flour (or rolled oats for gluten-free)
  • 1/4 cup melted butter or coconut oil
  • Optional: 1–2 cups mini marshmallows (added near end)

Instructions

  1. Grease the inside of a 5–6 quart slow cooker with butter or non-stick spray.
  2. Peel and cube the sweet potatoes, then place them in the slow cooker with a splash of water or milk.
  3. Cover and cook on HIGH for 2–3 hours or LOW for about 4 hours, until the potatoes are soft and easily mashed.
  4. Drain any excess liquid if needed. Mash the sweet potatoes directly in the slow cooker.
  5. Stir in butter, brown sugar, vanilla, cinnamon, nutmeg, salt, milk, and eggs (if using). Mix until smooth and creamy.
  6. In a small bowl, combine the topping ingredients — chopped pecans, brown sugar, flour (or oats), and melted butter. Stir until crumbly.
  7. Sprinkle the topping evenly over the mashed sweet potato mixture.
  8. Cover and cook on LOW for another 30–60 minutes, until the topping is heated through and slightly set.
  9. If using marshmallows, sprinkle them on top during the last 10–15 minutes of cooking, allowing them to melt.
  10. Serve warm directly from the slow cooker or transfer to a serving dish.

Notes

  • Drain excess liquid before mashing to prevent a watery texture.
  • Use oats instead of flour for a gluten-free topping.
  • For dairy-free: substitute plant-based butter and milk, and omit eggs.
  • Add a hint of orange zest or a splash of bourbon for richer flavor.
  • To brown the topping, transfer to an oven-safe dish and broil briefly before serving.
